EVALUATION

This is an Nvidia Linux driver bug reported recently under Nvidia bugid:
  235482: Java/Swing/JOGL apps distorted (87.62, Linux)

The problem appears to be specific to GeForce 6200 and 6150 boards.  Fortunately,
the bug has been fixed in an upcoming driver release (95.60 and above).  There's
nothing we can do in the JDK to work around the problem, so folks will just have
to wait until the fixed driver is released (or just disable the OGL pipeline).
Closing as "not a defect", since this isn't a bug in the JDK.
